Two-part stone-grey epoxy putty for aquascaping and coral mounting. Kneads by hand, sticks underwater, and cures rock-solid so you can secure frags, stabilize rockwork, and blend seams with natural reef tones.
Reef-safe once cured; suitable for marine & freshwater
Underwater usable—bonds in wet/splash zones
Natural stone grey color camouflages joints on most rock
Work time ~5–10 min, initial set ~15–30 min, full cure ~24 hrs
Adheres to rock, ceramic, glass, acrylic, most plastics, and PVC
Mount SPS/LPS/soft coral frags to plugs or live rock
Lock rocks to prevent topples; reinforce arches/ledges
Fill small gaps, tidy seams, and disguise plumbing holes

Turn off flow near the work area.
Slice equal parts; knead until uniform grey.
Press onto clean, roughened surfaces; hold 30–60 sec to tack.
Restore flow after 10–15 min; avoid heavy handling until cured.
For fast grab on frags: add a dab of superglue gel on each side of the putty (“glue–putty–glue”).
Skimmers may react temporarily; run carbon if needed.
